Abstract

The invention provides a preparation method of a continuous carbon fiber enhanced copper-based composite material. A method of adhering and curing copper powder on the surface of a continuous carbon fiber through organogel is adopted, the thickness of a copper layer adhering to the surface of the carbon fiber can be controlled, and therefore the content and the interval of the carbon fiber in a composite material after hot pressing sintering are controlled, so that the carbon fiber is distributed in a copper base body in parallel, and the copper-based composite material high in carbon fiber content can be prepared. According to the preparation method, a carbon fiber surface copper plating process complicated in process is omitted, cost is extremely low, operation is easy, and industrialized production can be achieved; and the electrical conduction performance and the strength of the carbon fiber enhanced copper-based composite material obtained through the preparation method are obviously superior to those of a carbon fiber enhanced copper-based composite material prepared through an existing impregnation method, and broad application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a preparation method of continuous carbon fiber reinforced copper matrix composite material. Background technique [0002] Carbon fiber reinforced copper matrix composites combine the characteristics of high specific strength, specific modulus, and low thermal expansion coefficient of carbon fibers. On the premise of ensuring the conductivity of copper, they also have high strength, high thermal conductivity, wear resistance, The advantages of ablation and welding resistance have been widely used in electronic component materials, electrical contact materials and wear-resistant devices and other fields. Carbon fiber reinforced copper matrix composites have good designability, and copper matrix composites with both electrical and mechanical properties can be prepared by controlling the content and distribution of carbon fibers. The content and arrangement o...
